To undistort. Put a blackside node. After the input.
Apply Lens disortion. To undistort. Enlarge the plate after the lens distortion to see hidden edges. Using reformat. Eg. Scale by 1.1. Using centred reformat. Preserve bounding box on.You will should now see the whole plate with black edges undistorted. This is yr new over scanned undistorted plate format. You can now comp within nuke or tracking software. To get back to original format. Redistortion. Reformat back to the orginal size by the calculation 1 divided by the previous scale format, centred. eg 1/1.1. With bounding box on. Apply the inverse lens distortion. You should now be back to the original... You can add an additional crop if you want.
